Western Massasauga

Sistrurus catenatus

Description:

The adults are not large, ranging from 60 to 75 cm (24 to 30 in) in length.[5] The color pattern consists of a grey or tan ground color with a row of large rounded brown/black blotches or spots down the center of the back and three smaller rows of alternating spots down each side. Solid black melanistic examples are also known, as well as cases where the back blotches join with those on the sides. Young massasauga are well-patterned but paler than the adults. This is the only Ontario snake with vertical pupils.[citation needed] It has heat-sensing pits on each side of its smallish head, the scales are keeled and the anal scale is single.
